For Fun.... Here is the Akro Agate glass that I identified..... I have a set of 4. They are 4.25 high and 3.25 wide at the mouth. Thought they were mid century when I bought them, but based on company history they are most likely pre WW2, as the company had financial difficulties after WW2 and stopped production by 1949. They then sold existing inventory until they closed in 1951.
The green feet are fused to the body....
I am like you Anne, The more I learn, the more I realize I do not know.......
